R package learningtower: Exploring standardised test scores across the globe

Introduction

The Organization for Economic Cooperation and Development (OECD) is a global organization that aims to create better policies for better lives. Their mission is to create policies that promote prosperity, equality, opportunity, and well-being for all.

PISA is one of the OECD’s Programme for International Student Assessment. PISA assesses 15-year-olds potential to apply their knowledge and abilities in reading, mathematics, and science to real-world challenges. The OECD launched this in 1997, it was initially administered in 2000, and it currently includes over 80 nations. The PISA study, conducted every three years, provides comparative statistics on 15-year-olds performance in reading, maths, and science.

Summary

Figure 1 shows an interactive plot of the palmerpenguins data (Horst, Hill, and Gorman 2020), made using the plotly package. This data features three penguin species which has a lovely illustration by Alison Horst in Figure ??.

p <- penguins %>% 
  ggplot(aes(x = bill_depth_mm, y = bill_length_mm, 
             color = species)) + 
  geom_point()
ggplotly(p)

Figure 1: A basic interactive plot made with the plotly package on palmer penguin data. Three species of penguins are plotted with bill depth on the x-axis and bill length on the y-axis. When hovering on a point, a tooltip will show the exact value of the bill depth and length for that point, along with the species name.
